The Decision: Finding the Right Andon Tower for Your Workstation
Industrial signaling doesn't have to be complicated, but choosing the right tower light can feel that way. You need a unit that clearly shows machine status, assembly line calls, or workflow states at a glance, and possibly with an audible alert. These two options take different approaches: one is a five-tier USB-powered tower with a built-in buzzer, the other is a four-tier aluminum-pole tower at a lower listed price.
Quick Verdict
Go with the 5-Stack USB LED Andon Tower Signal Light if your priority is multiple color tiers plus an audible buzzer in a USB-powered unit. Choose the ANDONT Industrial 4 Stack Andon Tower Signal Light if you want a four-stack tower with an aluminum pole and prefer the lower listed price.

It also lists assembly line call systems and CNC machine status alert compatibility, making it a fit for workstations that need both visual and audible status.

Product Notes
5-Stack USB LED Andon Tower Signal Light with Buzzer

This is the more feature-complete option if you need five distinct color layers plus sound. The listed price is $177.99, and you get a five-tier tower in red, yellow, green, blue, and white, along with an 85dB buzzer. The USB 5VDC approach avoids high-voltage wiring; the package includes a standard 9-foot USB cable and an adjustable bracket. It is aimed at assembly line call systems and CNC machine status alerts, which makes it easy to see where it fits. The trade-off is the higher listed price and the California Prop 65 warning that accompanies the listing. If your environment already uses USB-powered indicators and you want audible alerts in one unit, this is the one to choose.
ANDONT Industrial 4 Stack Andon Tower Signal Light, Aluminum Pole

If your main need is a four-stack signal tower and you want the lower listed price, this ANDONT unit is the direct alternative. The aluminum pole is called out right in the title, and the item is listed as new. The four-stack format gives you a multi-tier display for machine status or assembly line signaling, and the aluminum construction is the defining detail. The main compromise is the number of signal positions: four tiers rather than five, which may matter when you need more separate status layers.
Final Choice by Use Case
- Choose the 5-Stack USB LED Andon Tower Signal Light when you need five distinct color states, a built-in buzzer, and USB convenience in one unit. The higher listed price buys more signaling layers and an audible alert.
- Choose the ANDONT Industrial 4 Stack Andon Tower Signal Light when a four-tier tower with an aluminum pole fits your line and you want the lower listed price. It's a simpler four-stack take on the same andon concept.
